: After downloading, look at the file name. If it looks like 2021P5 (1).rar.exe , do not open it . A real archive should end only in .rar .
Windows and Mac don't always open .rar files natively without extra tools. : Use 7-Zip (free/open source) or WinRAR.
Once you're on the hosting site (like MediaFire, Mega, or Google Drive):
: If you found the link on a random site, copy the URL and paste it into VirusTotal to see if the hosting domain has been flagged for malware. 2. The Downloading Process
: Sites often have "Start Download" ads that look like the real button. The real download button usually matches the site's UI and shows the file size (e.g., 2021P5 (1).rar - 45MB ).
